Explanation / Answer

Shopper (T) = 428

Let the total shopper be T

Purchased and satisfied with service = PS

Purchased and not satisfied with service = PNS

Not Purchased and satisfied with service = NPS

Not Purchased and not satisfied with service = NPNS

T = PS + PNS + NPS + NPNS

Given

Shopper made a purchase : PS + PNS = 216

Made a purchase and not satisfied with service : PNS = 48

PS + PNS = 216

PNS = 48

PS = 216 - 48 = 168

Given, Shopper satisfied with service : PS + NPS = 296

NPS = 296 - 168 = 128

T = PS + PNS + NPS + NPNS = 428

168 + 48 + 128 + NPNS = 428

NPNS = 84

(a) PS = 168

(b) PS+NPS+PNS = 344

(c) NPS = 128

(d) NPNS = 84
